^ Even fully PvP fit the Viper scarcely drops below 650.
A lucky ram will kill it off sure, but more or less every projectile weapon, gimbal or turreted, let alone fixed are nothing more than a handicap. With lasers being more or less useless it can make a lone pilot a threat, if you're unlucky enough to run into four with good pilots, you either die or run, it does'nt matter how good you think you are or your ship is.
Not sure about a viper pvp build, seeing its agility is somewhat lacking, a chiefbeef outturns it.
